GeoGebra Best Fit Curves

The video tutorial demonstrates how to use GeoGebra to plot points, create a list of points, and find curves of best fit. It covers using the tools in GeoGebra to create a list of points, and then using the 'fit poly' function to find lines and curves of best fit, including linear, quadratic, and cubic fits. The tutorial also shows how these fits adjust dynamically when points are moved.
